Alter criteria for conflicts on type:object, style:form, explode:true #15

Currently we consider two parameters to conflict if

• Both arein:query
• Both are style: form
• Both are explode:true
• At least one can be type:object

However, if the one/both that is/are type:object specify additionalProperties:false then and only then, if their properties do not have conflicting names, they can be discerned from each other.
